SPEGIFCATION forming part of Letters Patent No. 608,992, dated August 9,1898.

Application filed December 28, 1897. Serial No. 663,890. (No model.) n

To ctZZ whom t may concern:

Be it known that we, LUDGER A. O. NICOL and EUGENE AYOTTE, subjects ofthe Queen of Great Britain, but residing at Lowell, county of Middlesex,and State of Massachusetts,have invented an Improvement in Spindles andBearings, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawroings representing like parts.

This invention relates to spinning-spindles, and has for its object theproduction of novel means for supporting the bolster within its case andcontrolling the vertical adjustment I5 of the bolster in a simple andeective manner, the change in the'vertical position of the bolster tosecure the proper fit of the pintle of the spindle therein being readilyaccomplished.

2o In accordance with our invention the bol-` ster is supported by acam-surface located at' the upper end of the bolster-oase and inclined'relatively to the vertical axis of the latter, so that by altering thepoint of engagement of` the bolster and cam-surface the position of thelatter is changed vertically.

Figure l, in vertical section, represents a spindle and bearing with oneembodiment of our invention applied thereto. Fig. 2 is a de- 3o tail inelevation of theupper end of the bolster-case. Fig. 3 is an'elevation ofthe bolster-support shown in Fig. l, and Fig. 4 is a sectional detail ofa modification to bedescribed.

' 35 Referring to Fig. l, the spindle S, having a tapering pintle and awhirl W, the bolster-r case A, having a threaded shank A to extendthrough the rail C, the retaining-nut A2, and

the bolster B, having within the ease a taper- 4o `ing bore to fit thetapering pintle of the spindle, may be and are of well-known or usualconstruct-ion.

The base of the bolster-case is shown in Fig. l as provided with anupturned annular` flange a, embraced by the extended base CZ of a tubeD, surrounding and snugly fitting the exterior of the case, the upperend of the support-being inclined or slanted, as at d', and preferably`serrated or roughened, as best 5o shown in Fig. 3. At its upper end theb01- ster-case has a longitudinal slot a' therein to receive a pin orprojection b on and projecting laterally from the upper end of thebolster B and adapted to rest on the cam-surface formed by the inclinedtop of the bolster-support D. l

The lowest part of the cam-surface is shown in Fig. l as in engagementwith the projection b, and it will be obvious that by turning thesupport more or less the projection will en- 6o gage a higher part ofthe cam-surface, so that the bolster will be elevated and supported in ahigher position, to thus adjust the bolster to the pintle of thespindle. Y

The slot in the bolster-case through which the projection b extendsprevents rotation of the bolster with the spindle, while the serrated orroughened character of the cam-surface prevents accidental rotativemovement of the bolster-support. `A step or end bearing 7o F for thespindle is located in the bolstercase independent of the bolster andbolstersupport.

Instead of making the controlling-cam as part of a different member, asin Fig. l, the top of the bolster-case itself may be inclined, as atc?,Fig. 4, and more deeply notched, as at a6, to receive the projection onthe bolster, to thus not only control the vertical adjustment ofthe bolster, but also to prevent its 8o rotation. In this construction thebolster is turned relatively to the cam-surface to eect verticaladjustment of the bolster.

` Having described our invention, what we claim, and desire to secure byLetters Patent, 8 5 1s-- 1. Abolster-ease, a cam located at the upperend thereof, a bolster freely suspended from and supported by the cam,relative partial rotation of the cam and bolster eecting ver- 9o ticaladjustment of the bolster, and means to normally prevent such relativerotation.

2. A bolster-case provided at its upper end with an inclined, serratedbolster-support, and a bolster having a lateral projection to 9.5 engagethe bolster-support and be sustained thereby in vertically-adjustedposition.

3. A bolster-case and a verticallymovable bolster therein, and aconcentricbolster-support having a cam to control the vertical adroojustment of and from which the bolster is suspended.

4. A bolster-case longitudinally slotted at its upper end, a surroundingbolster-support having an inclined upper end to control the verticaladjustment of the bolster, and a bolster provided with a lateralprojection to extend through the slot in the case and rest upon theupper end of the bolster-support.

5. A bolster-ease and a vertically-adjustable bolster therein, and arotatably-movable tubular bolster-support surrounding' the bol ster-oaseand having a Cam-surface adapted to engagea projecting portion of andsustain the bolster at its upper end, to control the vertical 15adjustment thereof.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing Witnesses.
